Diatomaceous Earth

Diatomite series products are carefully made from sediment of single -cell alga water plant, for the category of diatom its complexity and porosity, the diatomite products has the un-competitive filtrating capability and absorbent capability than any other filtrating medium, it is widely used for filtrate-supporting dose, stuffing and carrier. The diatomite series products made in our factory choose good quality diatomite ore sources which contained more than 90% of silicon dioxide as its raw material, adopting purified coal gas as its fuel, it is formed after burning in revolving stove and gas-dividing. This series of products has a light specific gravity, strong adsorption, its grains are reasonably distributed, it has a big areas, high hole ratio, high flow, good clarifying degree, lower-containing of heavy metal, stable chemical characters and good adaptability. Except alkali, hydrofluoric acid liquor, it can used reliably for liquid filtrating medium of all industry and catering treatment, medicine, and to be used as stuffing, carrier in the industries of chemical-industry, feed, building material. The diatomite based products can be divided into the following three categories by production process: I. Dried product: after the raw diatomite is dried under 100 o C to 300 o C, and then purified by high pressure gas flow pulverization, the product can be made by classification, it appear grey white-light yellow. II. Roasted product: The product is made through roasting the cleaned diatomite under high temperature of 700 o C-900 o C, high pressure gas flow pulverization and classification, it appears orange and brown. III. Melting aided roasted product: The cleaned diatomite is mixed with proper amount of melting additive, and roasted under 900 o C-1200 o C, pulverization and classification, the product appears white. As filter aid material for food processing,widely use in cider, corn syrup, fruit juices, sugar, pectin, citric acid, wine, vegetable juices, beer, lard, molasses, soft drinks, casein, vegetable oils, edible oil; for pharmaceutica in processes of enzymes, epsom salt, penicillin, streptomycin,water treatment; sizing, oil recovery, pool water treatment, greases, solvent recovery, disposal wells; for chemicals as iorganic cemicals, rsins, oganic chemicals, acid, polymers, polyethylene, brine, adhesives, titanium dioxide, fertilizers. waste disposal; waxes, oils, varnish, gums, shellac, paint, etc. Natural Additives & Padding Materials for Catalyst, Pesticide, Fertilizer, Rubber, Plastic, Painting, Coating, Cement, Paper, Grinding, Glass Steel, Fodder, Feed, Ceramics, Detergent, Dispersing Agent, Cosmetics, Toothpaste, Others Uses.
